Weird exhaust smell with MMO
 
I decided to use MMO to premix this tank, and then i started noticing that my exhaust has this very odd smell :confused: The smell is not worth trying to explain. but have you guys ever had a weird smell using MMO????

QuagmireMan 10-19-04 11:52 AM

does it smell like cookies or farts?

Becuase it is one or the other :D

RotaryRyan 10-19-04 01:05 PM

yes, it smels just like cookies and farts, mixed. :rolleyes:NOT!!

Have you taken a good whiff of MMO? It has a distinctly sweet aroma. You'd swear it was a coffee sweetener/flavor.

Does your exhaust have a rich, full bodied aroma like a Starbucks late? :D

MMO smells like those old wax candys that are filled with juice!!

Anyway, what do you expect??? you added MMO to your fuel, and not expect a change in exhaust "scent"

Why are you using MMO for pre-mix anyway??

I have always used TC-W3 marine oil.

did you make poop candles?

Gregs 10-19-04 06:16 PM

lmfao you guys are too much :rofl:

CarlRx7 10-19-04 07:10 PM

dont use mmo as a premix. use it as a cleaner, 2oz to the tank and your good. you need to add the 2-stroke oil to the gas for premixing.

MMO works for premixing, 12,000 miles going strong, with nothing but premixing MMO on this motor!

RotaryRyan 10-19-04 11:33 PM

im gonna keep using MMO. I trust hornbm. not trying to be mean. It says on teh bottle that it lubricates.............

Dont reply with a stupid comment please:D

I was just wondering if any others experienced the weird smell. Or if it was something different making my exhaust have this odor. Is that alright with you??? :cool:

Now go away, or I'll wave a cheese flag at you!!!!

SS124A 10-20-04 06:39 AM

you guys must have a stigma against my reletively low number of posts.

If my old screen name was working I am sure i would not be getting this level of disrespect. I am on here to help, not to be a troll.

IF you are running Pre-mix i suggest you look into the TC-W3.. it is far cheaper and actually designed to be a pre-mix. I have used it in my roadrace, autoX and street rotaries for years.

research the MMO and see if creates a sludge after being burnt a while.

as for a smell from the exhaust, what ratio of MM0 to fuel are you using.

Another idea to get rid of pre-mixing your sump oil is to get an OMP adaptor from rotaryaviation that meters a seperate supply of 2 cycle oil, such as TC-W3... into the engine for proper pre-mix.

Think about it.. wouldn't it make sence to consider an "aviation" component or suggestion than someones off the cuff decision to use MMO? When/If you engine blows, I am much more fond of the idea of it dying on track where i can roll safely to the side, than at 30000 +
feet. (here is a link if anyone would like to see it.) {http://www.rotaryaviation.com/oil_injector_pump_adaptors.htm}

This being said,.... I use MMO too... only occassionally in large doses to clean the inside of the trocoide surfaces... just before replacing sparkplugs

RotaryRyan 10-20-04 06:49 AM

Yeah ive seen those MOP adapters. They look cool. Ive always wanted one, just never bought one.

Oh, and no hard feelings. I dont even have a cheese flag to wave at you:rlaugh:

SS124A 10-20-04 07:07 AM

lol ok, WTF

I can picture the french guy in monty pythons holy grail waving one when he says "...that he farts in my general direction..." Or maybe it is still too early.
